I haven’t hosted my own matrix server yet. is it safe to join an instance? I don’t really know how private that would be. the question is when I signup/login would I be giving out my IP? is the metadata private? sorry for asking this, I’m just a bit paranoid
For me e2ee on XMPP with OMEMO works fine, never had problems with it. But I guess your best experience will be if both sides use the Conversations client on Android.
